The survey of 502 likely Dem primary voters was conducted April 16-17. The polling memo doesn't include a margin of error, but the results appear to be consistent with a public poll that came out earlier this week.

The polling memo from the Garin-Hart-Yang Research Group says Barrett’s support is more firmly committed to him and that Barrett: leads among both men and women; has a 15-point lead among voters who signed a recall petition; and leads 44 percent to 31 percent among union members.

The memo also says Barrett leads Falk by more than 20 points in both the Milwaukee and Madison media markets, which comprise three-fifths of the expected primary vote.

The memo doesn't include the complete poll results or the questions asked.
